Help my GV80 2021 keeps having an issue with draining the battery and dealership has no clue nor we can figure out what is happening.. and this is only happening when I load the back of my SUV with a lot of supplies that I take down to my Mother and all of a sudden the car won't start if we have loaded the car to drive the next morning it's just dead..this just started happening about a month ago and always after have the back has been loaded up to drive to see my Mother the next morning the car just won't start like the battery has just been drained and it has to be charged.. the dealership said the battery was fine no issues yet something is draining the battery after it is loaded.. Does anyone know why this might be happening?

Is the rear boot light staying on when the rear is loaded?

I have the same vehicle but have not experienced that particular problem. I did, however recently change out the battery, and got pretty familiar with the set up in battery compartment under the rear right tire cover area. The tolerances are close and the aux fuse panel there is a bit of an afterthought kludge--with the only support being the positive terminal and a little plastic foot opposite it. If your problem only happens when the car is loaded, I would check to see if somehow the weight in that area is causing a short--either of the cables onto the body/frame or with the battery tie-down bracket, or if it is placing too much pressure on that little circuit board. Also check to make sure all the cable connections are tight in that area. You might try loading the car away from the back right corner where all those connections are located. Also, go out after the car has been fully loaded and sitting for an hour or so at night in the dark and make sure the hatch lights are not on due to a misaligned closure or switch slightly out of tolerance that the added weight triggers. Good luck ! Please post your problem identification and solution if and when you locate it....

no it was a battery short and now has been fixed they had previously checked the battery and said it was fine but they did a long test on it at the dealership and it had a short and it's now working great!
